.Net System.OutOfMemoryException Filling A Datatable?

Sep 24, 2009

I need to extract data from a .dbf file and transform it into xml. I wrote a routine that does it just fine. However now we are encountering very large .dbf files - like 2GB +. And this code throws an OutOfMemoryException on those files.

Public Function GetData() As DataTable

Handling System.OutOfMemoryException In .NET?

Jul 22, 2009

I have a datagridview that has 65000 rows and 200 columns. I need to extract unique rows from the datagridview based on some sort of relevancy percentage.

While processing these rows it gives me an error "System.OutOfMemoryException" at around 47000 row. I searched for this exception over internet and found that it is related to RAM. I have 4GB RAM and my OS is Vista. However it would be used by people having as low as 512 MB RAM.

Jan 23, 2009

I'm downloading a bunch of files from a URI but when they get big, I get an utOfMemoryException. I thought at first it was MemoryStream error but I'm pretty sure now that the error is rooted in the declaration of an array of Bytes that's too large. (Half a gig is fine, 1.7 gig is not.)

Error 'Exception Of Type 'System.OutOfMemoryException' Was Thrown'

Feb 22, 2011

I'm prompted with this error 'Exception of type 'System.OutOfMemoryException' was thrown' it was thrown when filling a dataset with 400,000+ records. And I think obviously is about memory matter because of the number of records to be transfer.My program goes this way.. after filling a dataset from a table it will transfer all data into another table. Now my question is, Is it possible in vb.net that while filling a dataset it transfers the record immediately into another table? Please give me an idea on how to do this.

.net - SQLDataAdapter Filling Datatable With Primary Key Produces Error And Exits Sub?

Aug 12, 2011

Ok so this is going to take some explaining. The process I am trying to do is grab data from a table function in SQL and then fill a dataset with the returned values. I then have to run this query twice more to query an alternative number table. Then add to the same table as the previous queries.This needs to be as fast as possible, so I am currently using an adapter.fill to populate the datasets and then a dataset.merge to put them all into one table.

The problem is the query can return duplicates which waste time and space, because of this I made column 3(part_ID) the primary key to stop duplicates.When this is run with the .merge it quits at the first instance of a duplication and doesn't continue with the population.

Error "Exception Of Type 'System.OutOfMemoryException' Was Thrown." When Try To Read 100MB File

May 4, 2012

i want to ask about read file and then convert to binary i am using this code

Function readd(ByVal path As String, Optional ByVal Separator As String = " ")
' Store the line in this String.
Dim line As String

[code].....

it works fine to read small file, example 2MB file, etc but it get error "Exception of type 'System.OutOfMemoryException' was thrown." when try to read 100MB file i think the error code because the file is too big

For Each Character As Byte In ASCIIEncoding.ASCII.GetBytes(line)
oReturn.Append(Convert.ToString(Character, 2).PadLeft(8, "0"))
oReturn.Append(Separator)
Next

how can i read 100MB or bigger file?or maybe is it another method / code to read a file and convert it into binary?
